The complete manuscript should be submitted to the Editorial Office via E-mail whenever possible. In this case it is not necessary to send a printed copy of the manuscript. The author will receive a notification that all parts of the manuscript are readable or, if any problems arise. All parts of the text must be double-spaced and margins of at least 2 cm should be all around each sheet.

The manuscript should be assembled in the following order: title page, abstract, keywords, introduction, experimental part, results and discussion (including conclusions), acknowledgement (optional), references, tables, figures and figure captions, schemes and formulae. Results and discussion may be combined into a single section. Pages should be numbered consecutively from the beginning (title page) to the end.

Title: It is important that the title of the manuscript should reflect concisely the purpose and results of the investigation in order to provide maximum information for a computerized title search.

Author names and affiliations: This should be followed by the name(s) and complete address of the author(s). Corresponding author must be clearly indicated who is willing to handle correspondence at all stages of refereeing and publication, also post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.

Abstract: Every paper must be accompanied by an abstract. A concise and factual abstract consisting of one paragraph is required (100-200 words). The abstract should state briefly the scope, the principal results and major conclusions. Abbreviations and reference citations should be avoided.

Keywords: Immediately after the abstract, provide a maximum of five keywords, avoiding general and plural terms and multiple concepts (avoid, for example, 'and', 'of').

Introduction: State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Experimental: This should be presented as a clear and detailed description of experimental procedures and analytical conditions to enable readers to carry out similar work. Supply sample preparation procedures, name, model and configuration details of equipment used, and data handing methods.

Results and discussion: This should explore the significance of the results of the work, not repeat them.

Conclusion: A short Conclusions section is to be presented and should be divided into specific points.

Acknowledgement: Place acknowledgements, including information on grants received, before the references, in a separate section, and not as a footnote on the title page.

References: Responsibility for the accuracy of bibliographic citations lies entirely with the authors. Please ensure that every reference cited in the text is also present in the reference list (and vice versa). Unpublished results and personal communications should be avoided. Indicate references by number(s) in square brackets in line with the text. Number the references (numbers in square brackets) in the list in the order in which they appear in the text.

Tables: Tables should be typed in double spacing on separate sheets and provided a suitable heading. Tables should be clearly referred in the text by using Arabic numerals. Each table should have a title that makes the general meaning understandable without reference to the text.

Figures: Figures should be submitted either as original art work or as high-quality reproductions. Figures should be numbered consecutively; the captions should be typed on a separate sheet and grouped with the Figures at the end of manuscript.

Nomenclature, units and symbols: Follow internationally accepted rules and conventions: use the international system of units (SI).

Text Preparation: The final text should be submitted by e-mail as a WORD processor (*.doc file). Figures should be given in JPG format in high resolution (at least 300 dpi) or Excel files.
